Nothing can take the place of persistence.

This is the mark of a really admirable man: steadfastness in the face of trouble.

Football is like life—it requires perseverance, self-denial, hard work, sacrifice, dedication and respect for authority.

Faced with a mountain, I will not quit. I will keep on striving until I climb over it, find a path through it, tunnel under it, or simply stay and turn it into a gold mine.

To remain indifferent to the challenges we face is indefensible. If the goal is noble, whether or not it is realized within our lifetime is largely irrelevant. What we must do therefore is to strive and persevere and never give up.

We can do anything we want to if we stick to it long enough.

Limitations are merely opportunities to grow. I use them as stepping stones to success.

Success is simple. Do what's right, the right way, at the right time.

Think twice before you speak, because your words and influence will plant the seed of either success or failure in the mind of another.

Before a man can accomplish anything of an enduring nature in the world, he must first of all acquire some measure of success in the management of his own mind.

The man who earns a million, but destroys his health in the process is not really a success.

If you want to succeed you should strike out on new paths, rather than travel the worn paths of accepted success.

I owe my success to having listened respectfully to the very best advice, and then going away and doing the exact opposite.
